When compiled with GCC 4.0, a latent bug was exposed where both SparcV9
...
and the target independant register allocator were both using a class named
'LiveRange'. This lead to the target independant code calling code in the
SparcV9 backend, which crashed. Fixed by renaming SparcV9's LiveRange to
V9LiveRange.

Handle some more real world cases of rlwimi. These don't come up that

regularly in "normal" code, but for things like software graphics, they

unsigned short Trans16Bit(unsigned srcA,unsigned srcB,unsigned alpha)
{
unsigned tmpA,tmpB,mixed;
tmpA = ((srcA & 0x03E0) << 15) | (srcA & 0x7C1F);
tmpB = ((srcB & 0x03E0) << 15) | (srcB & 0x7C1F);
mixed = (tmpA * alpha) + (tmpB * (32 - alpha));
return ((mixed >> 5) & 0x7C1F) | ((mixed >> 20) & 0x03E0);
}
We now generate:
